Interesting Fact: Your tongue emits a dim amount of light when your eyes are closed

Did you know when you close your eyes and stick your tongue out, your tongue actually emits a very dim amount of light?

Go into the bathroom, shut off all the lights, and take a pic of your face with your eyes closed and tongue out. You'll have to mess with it in photoshop, but you can catch a very dim amount of light emitting from your tongue.
